We could be seeing flexible devices pretty soon as a group of South Korean scientists from the Ulsan National Institute of Science and Technology, have developed the world’s first imprintable and bendable lithium-ion battery according to the Korean Yonhap News Agency.
The new rechargeable batteries use nanomaterials that are applied to any given surface to create fluid-like polymer electrolytes, unlike conventional batteries that use liquefied electrolytes. This gives the battery more stability and makes it bendable. “Conventional lithium-ion batteries that use liquefied electrolytes had problems with safety as the film that separates electrolytes may melt under heat, in which case the positive and negative may come in contact, causing an explosion,” said the Ministry of Education, Science and Technology, who partially funded the research.
“Because the new battery uses flexible but solid materials, and not liquids, it can be expected to show a much higher level of stability than conventional rechargeable batteries.”
Such a development could prove useful for manufacturers looking to develop flexible mobile devices, like the prototypes displayed by Samsung at CES. Though other types of flexible batteries have already been in existence, for example S. Korean LG Chem’s cable battery, which can be bundled and even twisted into knots.
